BoxLang 1.7.0 Delivers Streaming, Distributed Caching, and Enhanced JVM Performance

Dynamic JVM Language Adds Server-Sent Events, JDBC Cache Store, and AST Generation Capabilities

Houston, TX – November 7, 2025 – Ortus Solutions announced the release of BoxLang 1.7.0, a major update to its modern dynamic language for the JVM that delivers enterprise-grade capabilities for building real-time, horizontally scalable, and AI-driven applications.

This release introduces native Server-Sent Events (SSE) for real-time streaming, JDBC-powered distributed caching, Abstract Syntax Tree (AST) programmatic access, and bytecode compatibility versioning—alongside extensive performance optimizations across the runtime.

Real-Time Streaming with Server-Sent Events

The centerpiece of this release is full Server-Sent Events (SSE) integration via a new SSE() built-in function and an enhanced Emitter system. These additions empower developers to build real-time, event-driven applications such as AI chatbots, live analytics dashboards, progress streams, and notification services.

Version 1.8 will extend this with an upcoming SSEConsumer() API, enabling runtime-to-runtime event consumption for distributed systems.

// Stream analytics data in real time
SSE(
    callback : ( emitter ) => {
        var startTime = now();
        while ( !emitter.isClosed() && dateDiff( "s", startTime, now() ) < 300 ) {
            emitter.send({
                activeUsers : getActiveUserCount(),
                requestsPerSecond : getCurrentRPS(),
                avgResponseTime : getAvgResponseTime(),
                timestamp : now()
            }, "metrics");
            sleep(5000);
        }
        emitter.close();
    },
    async : true,
    keepAliveInterval : 15000
);

The implementation includes async execution, automatic keep-alive, client disconnect detection, CORS support, and automatic chunking for messages exceeding 32KB—ensuring efficient, resilient streaming at scale.

// Stream AI responses token by token
SSE(
    callback : ( emitter ) => {
        var response = callAIService();
        while ( !emitter.isClosed() && response.hasMoreTokens() ) {
            emitter.send( response.getNextToken(), "token" );
        }
        emitter.send({ complete : true }, "done");
    },
    async : true,
    keepAliveInterval : 30000,
    timeout : 300000
);

Enterprise-Ready Distributed Caching

BoxLang 1.7.0 debuts the JDBC Cache Store, a robust distributed caching solution that enables shared caches across multiple BoxLang instances using enterprise databases such as Oracle, MySQL, PostgreSQL, Microsoft SQL Server, Apache Derby, HSQLDB, and SQLite.

// boxlang.json
{
  "caches": {
    "distributedCache": {
      "provider": "BoxCache",
      "properties": {
        "objectStore": "JDBCStore",
        "datasource": "myDatasource",
        "table": "boxlang_cache",
        "autoCreate": true,
        "maxObjects": 1000,
        "evictionPolicy": "LRU"
      }
    }
  }
}

The JDBC store includes automatic schema creation, database-specific SQL optimization, eviction policy support (LRU, LFU), and Base64 object serialization for complex types. All cache stores now implement isDistributed() for ecosystem introspection.

Advanced Code Analysis with BoxAST()

Developers can now access BoxLang’s internal Abstract Syntax Tree through the new BoxAST() built-in function. This feature supports the creation of linters, formatters, migration tools, and refactoring utilities—making it invaluable for static analysis and CFML-to-BoxLang transitions.

// Parse BoxLang code
ast = BoxAST( source : "x = 1 + 2; y = x * 3;" );

// Or use the convenient member method
ast = "function hello() { return 'world'; }".toAST();

// Parse from files
ast = BoxAST( filepath : "myScript.bx" );

// Return as JSON for external tools
astJson = BoxAST(
    source : "function hello() { return 'world'; }",
    returnType : "json"
);

// Parse CFML code for migration tools
cfAst = BoxAST(
    source : "<cfset x = 1><cfoutput>#x#</cfoutput>",
    sourceType : "cftemplate"
);

BoxAST() supports BoxLang script and template syntax, as well as CFML/ColdFusion code parsing for migration purposes, returning structured, JSON, or text output.

Bytecode Compatibility Versioning

To enhance module stability and cross-version reliability, BoxLang now implements bytecode compatibility versioning, ensuring that compiled artifacts remain consistent and reusable across multiple runtime releases—a major improvement for module authors and enterprise teams maintaining large applications.

Performance & Stability Enhancements

Version 1.7.0 delivers substantial runtime performance boosts, including:

• ⚡ Faster Scheduled Tasks via optimized concurrent maps
• 🚀 Improved Static Initializers for class loading
• 💾 Optimized ASM Bytecode Generation eliminating intermediate disk writes
• 🔁 Cache Store Enhancements across all providers

Additionally, over 40 bug fixes improve database interaction, file handling, HTTP services, CFML compatibility, and Windows platform support.

Open and Professional Ecosystem

BoxLang follows a professional open-source model with three editions: Open Source (Apache 2.0), BoxLang+, and BoxLang++.
The open-source core remains free, while commercial tiers provide support, advanced modules, and enterprise tooling—licensed fairly based on usage, not infrastructure.

New BoxLang+ exclusive modules include:

• 🧠 bx-redis – High-performance Redis integration
• 📊 bx-csv – Advanced CSV processing
• 🔐 bx-ldap – LDAP directory services
• 📈 bx-spreadsheet – Excel file operations
• 📄 bx-pdf – PDF generation

Future roadmap modules include bx-couchbase, bx-mongodb, and bx-elasticsearch.
